1. INTENDED USE Scales are designed for fast and precise measurements of weighed loads masses and direct commercial settlements. Tarring in full weighing range enables to determine net mass of weighed loads. Functions:

• backlight of display • level of filtration • autozero function • setting baud rate of transmission • continuous data transmission for RS 232 • automatic operation for RS 232 • designed printouts • designation minimum mass for function operating • counting pieces • +/- mass control • percentage deviation from standard mass • latch of maximum scale indication • automatic tare • memory of tare • Memory of 9 tare values • inscribing tare value • automatic scale switch-off • user calibration • Totalizing • Weighing animals

User functions may have attribute of accessibility. For this reason it is possible to adjust scale to individual needs to provide access to only these functions which are currently needed. Attribute determination accessible / inaccessible is possible in user menu and described in further part of manual.

2. PRECAUTIONS 2.1. Maintenance

A. Please, read carefully this user manual before and use the device according to its intended use.

B. Devices that are to be withdrawn from usage should be sent back to the producer or in case of own utilization do it according to the law.

2.2. Accumulator / battery pack The device connected to mains inteligently monitors the battery state and charges it if possible. After sudden lack of power supply from the mains the device automatically switches to accumulator without breaking operation. • Scales aquipped with indicator PUE C/31 (plastic casing) are devices

designed to be supplied from NiMH batteries (nickel-metal-hydrogen) with rated voltage of 1.2V, size R6 and capacities from 1800 to 2800mAh charged while connected to mains without stopping operation.

• Scales equipped with PUE C/31H and PUE C/31H/Z weighing

indicators (stainless steal housing) are devices designed to be supplied from SLA accumulators (Sealed lead acid type) 6V o and capacity 3 to 4Ah charged while connected to mains without stopping operation.

In case of an elongated storage period in low temperatures, it is not allowed the full discharge of the accompanied batteries.

The equipment including accumulators does not belong to your regular household waste. The European legislation requires that electric and electronic equipment be collected and disposed separately from other communal waste with the aim of being recycled.

- 6 -

Notice: Some symbols on accumulators identify harmful elements/compounds: Pb = lead, Cd = cadmium, Hg = mercury. 2.2.1. Power supply of weighing indicators in plastic casings Indicators in plastic casing are intended to be supplied from a power adapter or from NiMH rechargeable battery pack (standard equipment). New rechargeable batteries should be formatted according to the description in the chapter 14.4.4. of this manual.

Alternatively, you can use to power the device R6 size standard non-rechargible batteries. If you want to use normal batteries instead of rechargeable ones, proceed as follows:

• Before installing non-rechargeable batteries turn on the device and set <5.5.CHr6> to <no>, to switch off charging.

• Then install the batteries.

- 7 -

Installing batteries without changing <5.5.CHr6> to <no> may cause damage of batteries and the indicator.

2.2.2. Replacement of worn batteries Users have the ability to replace worn out batteries to new ones in weighing indicators PUE C/31 (plastic casing). Procedure:

• Open the lid of the chamber for batteries placed in the bottom of the indicator casing:

• Remove discharged and then insert new batteries into the chamber, according to given polarity (+/-):

• Close the lid of the chamber for batteries:

In PUE C/31H and PUE C/31H/Z weighing indicators (stainless steel housing) the worn out accumulator can be exchanged to a new one by the authorized service of the manufacturer.

2.3. Operation in a strong electrostatic field If the device is about to operate in a strong electrostatic field (e.g. printing houses etc.) it should be connected to the earthing. Connect it to the clamp terminal signed .

11. WEIGHING Put a load you want to weigh on the weighing pan. When the pictogram appears it means that the result is stable and ready to read. Special line scales should be loaded with intended loads: • For ramp scales (hand trucks used in meat industry) the platform

should be matched to the trucks with maximum weight and the wheels were close to the load-bearing sections:

• For pallet scales (load on euro-pallets put on by pallet trucks)

the middle foot of the pallet should not be supported while on the weighing platform:

• For beam scales – load of stiff, self-supporting structure

or in a stiff container:

- 20 -

• For four load cell platform scales (pit version) – loads carried and weighed together with trucks:

− Total weight of the truck and its load cannot exceed the maximum value of the scale range,

− Trucks are allowed to drive through without braking and accelerating with the maximum speed 2km/h,

− Platforms should be driven over only perpendicular to the edge of the platform, in order to uniformly load the scale,

− Loads should be stand steadily and slowly, − It is not permitted to push or pull loads on or from or over

the weighing platform.

11.1. Tarring In order to determine the net mass put the packaging on the pan.

After stabilising press - (Net pictogram will be displayed in the left upper corner and zero will be indicated).

After placing a load on the weight pan net mass will be shown. Tarring is possible within the whole range of the scale. After unloading the pan the display shows the tarred value with minus sign.

1. You cannot inscribe a new tare value when the tare value in memory is greater than zero. In the case of trying this the <Err3> message will be displayed and short audible signal will be emitted.

2. Users can also enter up to 9 tare values to the scale memory (see 15.10 of his manual).

- 22 -

11.3. Zeroing

To ZERO the scale press: . The scale will display zero and following pictograms: and . Zeroing is only possible within the scope of ±2% of full scale. While zeroing outside the scope of ±2% you will see <Err2>. Zeroing is possible only in stable state. Notice: Zeroing is possible only within the ±2% interval of the maximal range. If zeroing is performed beyond this range the <Err2> message and short audible signal will be emitted. 11.4. Weighings in two ranges Switching between the I range and the II range happens automatically (exceeding Max of the I range). Weighings in the second range is signalled by a pictogram in the top left corner of the display. Then weighings is done with the accuracy of the II range to the moment of returning to zero (autozero range ) where the scale switches back to the I range.

Fnnd no - filter disabled Fnnd YES - filter enabled

Return to weighing:

See - 10.2.2. 12.3. Autozero function The autozero function has been implemented in order to assure precise indications. This function controls and corrects „0” indication. While the function is active it compares the results continuously with constant frequency. If two sequentional results differ less than the declared value of autozero range, so the scale will be automatically zeroed and the pictograms and will be displayed. When AUTOZERO is disabled zero is not corrected automatically. However, in particular cases, this function can disrupt the measurement process e.g. slow pouring of liquid or powder on the weighing pan. In this case, it is advisable to disable the autozero function.
